Problems solved by technology

In the actual process, most of the research needs to be based on certain assumptions and preconditions, either to simplify the problem, or to set the delay distribution law or propagation mode in advance, so the established models and algorithms have strict requirements on the scope of use. , but the guidance for the actual production of transportation is insufficient

Embodiment

[0048] A method for establishing a high-speed train initial delay impact prediction model, including a method for establishing an initial delay impact train number forecast model and a method for establishing a total time forecast model for initial delay impacts; wherein, the establishment method for an initial delay impact train number forecast model includes the following step:

[0049] S101: Designate the station to be processed, extract the train sequence affected by the initial delay of the station to be processed, and obtain the data sample of the number of trains affected by the initial delay.

[0050] The initial delay, the sequence of trains affected by the initial delay, and the data samples of the number of trains affected by the initial delay will be described in detail below. In the actual operation of the train, the arrival time of the two trains at the station should at least maintain the minimum tracking interval time, usually the tracking interval time between...

Abstract

The invention relates to the technical field of transportation, and aims at providing a method for establishing a high-speed train initial delay influence prediction model. The invention comprises a method for establishing an initial delay influence train number prediction model and a method for establishing an initial delay influence total time prediction model. The method for establishing an initial delay influence train number prediction model comprises the following steps of: comparing different alternatives of the first machine learning classification model, selecting the final first machine learning classification model, and selecting the final first machine learning classification model as the initial delay affecting train number prediction model. The method for establishing an initial delay influence total time prediction model comprises the following steps of: comparing different alternatives of the second machine learning classification model, selecting the final second machine learning classification model, and selecting the final second machine learning classification model as the initial delay influence total time prediction model. As that model process of the invention is convenient, the number of trains affected by the initial delay and the total time are predicted.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a method for establishing a high-speed train initial delay impact prediction model. Background technique [0002] High-speed railway has a series of advantages such as good safety, fast delivery speed, high punctuality rate, large transportation capacity, and low energy consumption. The development of high-speed railway has greatly alleviated the shortage of transportation capacity and improved the scale and quality of my country's road network. It has played an important supporting role in the sustained and rapid development of the national economy. [0003] However, due to the complex operating environment of high-speed railways, high-speed trains will inevitably be affected by the external environment, internal system mechanical failures, and organizational management during operation, resulting in the actual arrival time of the train (actual departure time) and the plan...
